|The VOCALOID4 version of the original Rana vocal. Users can get a upgrade if they have all 30 tickets from the previous VOCALOID3 version registered from the Vocalo-P ni Naritai magazine. This is a cheaper method of obtaining the voice. In addition, more producers can now access her voice, both on a local Japanese scale and a world wide audience.|
